LIEBERT INTELECOOL2
Product Specification Sheet
Features/Options
• Self-Contained
All components are enclosed in the painted steel or optional
corrosion-resistant aluminum cabinet. The standard color for the
painted steel is tan, with optional colors available.
• Space-Saving Design
Mounted outside the shelter to save valuable space.
• Range of Capacities
Units are available in 2, 3, 4 and 5 ton 60Hz models, and 3, 4 and
5 ton 50Hz models.
• Compressor Options
A high-efficiency scroll compressor is standard on all models. It is
ideal in applications where noise is a factor because of its low
noise and vibration.
• Optional Compressor Location
• Evaporator Supply and Return Openings
Match industry standard dimensions.
• Easy to Install
Wired, piped, charged with refrigerant and factory-tested as a
LIEBERT INTELECOOL2
system to ensure trouble-free installation and startup.
2, 3, 4 and 5 Ton Models
• Outside Air Options
A fixed fresh air damper option allows for adding fresh air/pressurization. The Economizer option allows
for cooling using outdoor air when it is cool enough to meet the room conditions.
• Telecom Package “T-Pack”
This configuration incorporates popular telecom options: low pressure switch, fan cycle control and low
pressure bypass. Many other component options are also available.
• Control/Monitor Options
The Liebert Dual Unit Control™ thermostat can control two units and provides autochangeover control.
Other autochangeover control options are also available.
